| Abstract | ||
| The present work includes preparation and characterization of number of new complexes of ligand2(2,4-dinitrophenyl hydrazen) benzothiazole(L), which is synthesized by the reaction of 2-mercapto benzothiazol with 2(2,4-dinitrophenyl hydrazen) in an ethandic solution. Metal complexes have been synthesized from the reaction of ligand (L)with metalions CoCl2.2H2O,FeCl3.6H2O,MnCl2.H2O, CrCl3.6H2O,HgCl2,ZnCl2,NiCL2.These complexes were characterized by elementalanalysis, FT-IR, UV-visible spectroscopy,atomic absorption, magnetic moments and molar conductance measurements. It was concluded from the elemented analysis that all most chelatscompound has2-mercaptobebzothiazole been found to be (1:1)(Ligand:metal) molar ratio according to the preceding measurements,except Cr((ΙΙΙ)complexes have (2:1) )(Ligand:metal) molar ratio.The evidence from (IR) spectra show that in all complexes the ligand is coordinated via the thiazole nitrogen and exactly nitrogen atom of hydrazine so the complexes withMn(ΙΙ),Fe(ΙΙΙ),Co(ΙΙ), Zn(ΙΙ) & Hg(ΙΙ)are tetrahedral, the complex with Cr(ΙΙΙ) is octahedral and with Ni(ΙΙ) is square planer geometry. | ||
